TANK-CAR.

scenes,

To all whom it may concern: Be it known that l, lViLLrAM M. IZRICK- BAUM, a citizen of the United States of America, and a resident of Cleveland, in the county otCuyahoga and State oi Ohio, have invented certain nev and useful Improvements in Tank-Cars, of which the following is a specification.

My invention relates to improvements in tank-cars, and has for its object the production of eilicient means for mountin and sup porting the-tank upon the trucks of such cars.

A common anode, previous to my invention, of mounting tanks upon railway cars, has involved the provision of longitudinal ooden stringers and wooden aloutments respectively for engaging the bottom and ends of the tank. By reason of the fact that the metal tanks of commercial sizes are subject to very considerable expansion and contrac tion particularly throughout their length, amounting frequently to as much as an inch variation, it is found that the tanks-Work loose within their fastenin s, ,and become damaged because of this. ALccordingly, l

have lmproved upon the prior constructions in the manner set forth in the annexed specification and claims, and the embodiment of my invention may first be mentioned in a preliminary way by stating that the car trucks 'inount a superstructure, the principal members of which are two parallel channel irons or beams which carry a plurality of segmental cradles. The tank itself is supported within said cradles, while at eitherend of the tank are provided adjustable blocks, preferably secured to the channel members directly and by tie-rods, which blocks ordinarily are formed of cast iron and are provided with yielding bearing faces adapted to Withstand the end thrust of the tank. By means of colts and nuts, said end blocks are provided with adjustment longitudinal with respect to the tank.

. and other features, will be made the subject of'mcre explicit description, with the aid of the several figures in the accompanying sheet of drawings, wherein:

Figure I is a view in side elevation of a tank-car cquipped'in accordance with my in: vention. Fig. 11 is an enlarged view in side elevation,

These,

A artially brokenaway, of one of the end is ocks and its tie-rod connection. 7 Fig. H1 is a View in and elevation, showing 2%, twill need not he partioularized herein, for the reason that they are ,well known and form no partof this invention, but 1 have shown in Fig. I, the essential-features of an improved tank-car equipped with my improvements, While in .the remaining figures, these improvements are illustrated in their referred form. Referring then to the first figure of the drawings, it will be seen that two end trucks (4 support the tank-car; the

body of which is formed by two heavy longitudinal channel members or beams b united along their upper and lower flanges 1 b by transverse plates (2 0. Trans versely extending across the ear frame are shown four cradles 03 supported by the upper plates 0 and lower flanges Z) of the girders. Iron end blocks e are positioned at either end of the tank suitabl T reinforced as best shown in F igs. H and II, to withi stand the very considerable end thrust of,

said tank f. These end blocks are secured in place primarily by bolts e entering slotted openings in the flanges b of the girder frame. and plate 0. Moreover, tierods 9 extend backward upon either side and are suitably attached intermediately of the girders, as by the riveted plates 5 and cross bars 9 The ends of the tierods are threaded, whereon the bolts 9 are screwed.

Preferably the inner faces of the end,

blocks are equipped with a cushioning material it or" sernnresilient character, such as hair felt, which may well he of the initial thickness of an inch or more, to provide an equalizing and yielding hearing face for the end of the tank. This is desirable, for the reason that. in switching the cars and even I in' transit, they are subjected to heavy shocks, which tend longitudinally to dis place the tank, and it is desirable that these end blocks shall hear evenly upon the ends of the tank, and closely engage the same to avoid any movement or play.

From the foregoing, it will be appreciated that the tank is securely supported on the to suit climatic conditions, or the temperature of the tank-contents, and the resulting pied by the end blocks.

expansion or contraction of said tank. lfhus, simply by releasing the bolts 6, the end blocks may be drawn closely against the ends of the tank throu h the medium of the nuts g, or said'end bdocks may be relaxed if too much tension would otherwise be placed thereon. The. bolts 6 are then tightened in the adjusted positions occu- The tie-rods are so positioned as to transmit a large portion of the longitudinal strain or shock to intermediate portions of the girder-frame, ahd avoid the heavy impact which otherwise would be necessarily sustained by the extremities of said frame. Moreover, by providing the yielding face of hair felt, or "the like, slight Variations in the length of the tank will be compensated for by the yielding nature of this material, even under compression.

j Having now described the preferred embodiment of my invention, I here claim and desire to secure by Letters Patent, the following 1, in a tank car, the combination with a supporting frame carried by the trucks of car, of a tank mounted thereon, end blocks gaging the extremities of the tank and secured to the frame, connecting members' securing said end blocks intermef the frame, and means for secur: positive adjustment of said end 1 .bstantially as set forth.

frame forming the body of the car' a girder frame forming the body of the car and supported by the trucks thereof, of

a plurality of cradles thereon,- a tank positioned within said cradles, end blocks engaging the extremities of the tank, cushionmg members interposed between said end blocks and tank, connecting rods extending laterally from'said end blocks to points of attachment intermediate of the frame, slotted supports provided for said end blocks upon the extremities of the frame, and means for adjustably securing said end blocks to the connecting rods and extremities of the frame, substantially as set forth. v

4. In a tankcar, the combination with a girder frame forming the body of the car and supported by the trucks thereof, of a tank mounted upon said frame, adjustable end blocks engaging the extremities of the tank and secured directly to the frame, transverse supporting members positioned intermediately-of the frame, tie. rods uniting the end blocks and transverse members, and means for securing the positive adjustment of said end blocks with respect thereto, substantially-as set forth.
